Participation of the Aged in SSI
利用1975年3月当前人口调查数据，发现约50%符合条件的老年人未参与补充保障收入计划，参与概率与福利水平正相关，信息不足、污名化和官僚程序是主要障碍。
The Supplemental Security Income (SSI) program is the primary escape route from poverty for a significant number of the aged poor; yet approximately 50 percent of all those eligible are not enrolled. Analyses of data from the March 1975 Current Population Survey, reported here, reveal that individual participation probabilities are positively related to the level of available benefits. Other factors such as limited information, stigma, and the bureaucratic complexities of the enrollment process appear to be significant barriers to participation. Efforts to increase participation in SSI must concentrate on raising available benefits and reducing the barriers to participation.
